WATER-CLOSET COUPLING.

SPECIFICATION forming part of Letters Patent No. 712,012, dated October28, 1902.

Application filed May 22, 1902. Serial No. 108,503. (No model.)

To a whom it may concern.-

Beit known that we, EDMOND 0. SMITH, residing at Saugatuck, and CYRUS L.MEADE, Jr. residing at Westport, county of Fairfield,

State of Connecticut, citizens of the United States, have invented a newand useful Water- Closet Coupling, (Case A,) of which the following is aspecificatiom This invention relates to certain improvements incouplings for water-closets, and has for its object to provide acoupling between a soil-pipe and a ceramic bowl which shall bethoroughly sanitary, as the escape of sewergas is made impossible, offew parts, whichare relatively inexpensive and easily put together andthoroughly durable, as the bowl is not attached to the floor, but to ametal base, so that all difficulty in setting up and danger of breakageowing to unevenness of floors and their swelling, shrinkage, or settlingis avoided.

It is an essential feature of this invention that we produce awater-closet coupling in which the soil-pipe is secured to and suspend-2 5 ed from a metal base and without connection either with the floor orthe bowl.

WVith the above and other objects in view the invention consistsincertain constructions and in certain parts, improvements, andcombina'tions which will be hereinafter described and then specificallypointed out in the claims hereunto appended.

In the accompanying drawing, forming part of this specification, inwhich like characters 5 of reference indicate the same parts, the figureis a sectional view illustrating the mode in which we have carried theprinciple of our invention into effect.

A denotes a ceramic water-closet bowl hav- 4o ing a flange 10; B, ametal base having an upper flange 11 corresponding with flangelO uponthe bowl, and a lower flange 12, which rests upon the floor C; D, atwo-part clamp adapted to engage flanges 10 and 11 and secure the bowlto the base, and E is a soilpipe whose upper end is flanged over, as at13, as a means of rigidly securing it to the base.

The base Bis made in two parts, which are denoted, respectively, by 18and 19. The

lower part (indicated by 19) is provided with an internal shoulder 20and above said shoulder with a female thread 21, and the upper part(indicated by 18) is provided with a depending collar 22,.having a malethread corresponding with the female thread on part 19. As the bowl isnot attached to the base until after the latter is in position, it isobvious that the lower end of the collar may be turned down upon theflange of the soil-pipe just as tightly as may be required to insure aperfectly tight joint. Thenthe bowlis set upon the base, packing 15being interposed, and said partsare secured togetherby a clamp D.

In setting up a water-closet Where our novel coupling is used thesoil-pipe is passed up through the floor, the metal base placed over thesoil-pipe and secured in place, then the upper end of the soil-pipe isflanged over either upon an internal shoulder on the base or over thetop of thebase, so as to secure it thereto, and then the bowl is placedin position on the base and secured there by a twopart clamp engagingflanges on the base and bowl, respectively, as clearly shown in thedrawing, packing, as a gasket, being always used between the bowl andthe base.

We do not claim herein a closet-coupling comprising a soil-pipe having aflange for securing it in place, a metal base for attachment to thefloor and having a recess to receive the flange, and a ceramic bowlresting upon and secured to the base and having its weight supportedthereby, as the same forms the subjectmatter of our application SerialNo. 108,504, filed concurrently herewith.

Having thus described our invention, we claim 1. In a coupling of thecharacter described, the combination of a metal base formed of twointerlocking members having an annular space between them, of asoil-pipe having a flange fitting in said space and engaged by saidinterlocking members, and a bowl supported by said base.

2. In a coupling of the character described, the combination of a metalbase formed of two interlocking members, one of which is provided withan internal shoulder, of a soilpipe having a flange resting on saidshoulder and interposed between meeting faces of said locking members,and a bowl supported by said base.

3. In a coupling of the character described, the combination of a lowermember having an internal shoulder, an upper clamping member, asoil-pipe having a flange resting on said shoulder and engaged by saidclamping member, and a bowl supported by said clamping member.

4. In a coupling of the character described the combination with a metalbase consisting of a part 19 adapted for attachment to a floor andhaving an internal shoulder and a female thread and a part 18 having adepending collar threaded to engage the other part, of a soilpipeflanged externally to secure it to the shoulder and gripped between saidshoulder and collar, a bowl resting upon the base, and a clamp by whichthe bowl is secured to the base.

In testimony whereof We affix our signatures in presence of twowitnesses.
